I am going to answer this in bits and pieces because I am on my phone, not on my laptop.

Churchill wanted America to join WWII. Historians and those people who study these things say the British Empire would have won the war anyway - just 2 years later. Also, the biggest contribution was from the USSR, not from America. The USSR was also the first in Berlin.

Next, in communism, there is no government. All production is owned by collectives, and the collectives can definitely make a profit. Business cooperatives are based on the communist way if doing business. You have many very successful cooperatives in the States

A business does not need to make a profit. It needs to break even, and it needs to pay its staff well, and to allow the owner to earn a good salary. Year end profit is not necessary.
